Question

Using the given digits write the smallest and the greatest $5-\mathrm{digit}$ numbers. You repeat any one digit twice.

$4,3,2,6$.

Answer 1

We get the smallest number by putting the smallest digit at the ten thousands place and repeating it at the thousands place.

Therefore, the smallest $5-\mathrm{digit}$ number is $22346$.

Similarly, the greatest number is obtained by putting the greatest digit at the ten thousands place and repeating it at the thousands place.

Therefore, the greatest $5-\mathrm{digit}$ number is $66432$.
